CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 503,582, dated August 22, 1893.

Application iiled November 29, 1892. Serial No. 453,462. (No model.)

To all whom, it' may concern,.-

Beit knownthat I, JAMES B. DUKE, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Cigarette-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of cigarette machines in which a continuous filler of tobacco is inclosed within a continuous wrapper, and commonly known as continuous filler machines, and especially to that part of the machine known as the wrapping tube, in which the wrapper and filler are brought together and the filler inclosed within the wrapper.

The object of the invention is to provide an improved wrapping tube, and especially one affording more convenient access to the tiller during the wrapping operation than the wrapping tubes heretofore in use; and I attain this result by making the wrapping tube open at the side rearward of the point at which the edges of the wrapper are brought together, and preferably by providing an opening eX- tending through a considerable portion of the length of the tube between the rear end and this point and below the filler presser commonly used in such constructions, so that the tube may readily be cleared in case of obstruction, by running a clearer through the opening longitudinally of the tube. The construction of the wrapping tube is thus simpli fied also and a freer movement of the belt and wrapper secured. The tube maybe open on only one side, but is preferably made open on both sides.

The features forming my invention are applicable generally in continuous filler inachines employing a wrapping tube, and to wrapping tubes of different detailed constructions, but they will be illustrated as applied to wrapping tubes of the general construction of those used at the present time in the well known Bonsack machine.

Referring to the accompanying drawings forming a part of this speciicationzA-LFigure 1 is a side elevation showing in operation such parts of a cigarette machine as are necessary to illustrate my invention, the tube shown being of the preferred form, open at both sides. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a side View of the wrapping tube detached. Fig. t is a broken plan view of the same. Figs. 5 to 1l are cross sections on lines 5 to 11 respectively of Fig. l, looking to the left. Figs. 12, 13, and 14 are views corresponding respectively to Figs. l, 3 and 4, showing a modified form of tube, open only on one side. are cross sections on lines 15 to 19 respectively, of Fig. l2. Figs. 20 and 21 are views similar to Fig. 3, showing other modifications.

Referring to said drawings, A is the wrapping tube, and B the wrapper carrying belt, which two parts may be supported and the latter led through the wrapping tube and driven in the manner common in this class of machines. The continuous wrapper :c is led onto the carrying belt and advanced there by through the wrapping tube, and the filler y received thereon at the rear end of the wrappingtubein the usual manner. The construction of the wrapping tube in advance of the point at which one edge of the wrapper is turned inward, and the devices co-operating therewith for securing the wrapper by pasting or otherwise may be ofV any suitable construction, this part of the wrapping tube being shown substantially as in common use in the machine above referred to.

The present invention consists of improve ments in the rear portion of the wrapping tube, in which the wrapper carrying belt and wrapper are turned upward about the compressed iiller so that the wrapper will be in proper position for securing the edges at the forward part of the wrapping tube; and these improvements will now be described as applied to the special wrapping tube shown, from which description their application to tubes of other constructions will be understood.

Referring now especially to the construction shown in Figs. l to 11, in which the wrapping tube is open upon both sides, the body of the wrapping tube is formed in two sections arranged to leave a space between them opposite the filler presser a, this space extending preferably a considerable distance longitudinally of the tube,'and preferably from a point at or near the rear end of the tube, as shown.
